A model of elastic adhesive bonded joints through oscillation–concentration measures

An elastic–plastic interface constitutive model: application to adhesive joints

An interface constitutive model which accounts for both reversible elastic, as well as irreversible inelastic separation-sliding deformations at the interface prior to failure has been developed and implemented in a finite-element computer program. A set of experiments has been conducted to determine the constitutive parameters in the interface model for adhesivelybonded components made from an...

Reliability analysis of bonded joints with variations in adhesive thickness

Elastic-plastic Mode-ii Fracture of Adhesive Joints

A numerical study of the elastic-plastic mode-II fracture of adhesive joints is presented in this paper. A traction-separation law was used to simulate the mode-II interfacial fracture of adhesively-bonded end-notched flexure (E.N.F.) specimens loaded in three-point bending, with extensive plastic deformation accompanying failure. The fracture parameters for the traction-separation law were det...

Continuum damage modelling of environmental degradation in joints bonded with EA9321 epoxy adhesive

A mesh independent continuum damage model has been proposed to predict the residual strength of adhesively bonded joints by introducing a displacement-based damage parameter into the constitutive equation of damaged materials. Joints bonded with a ductile adhesive EA9321 were studied for a range of environmental degradation. The moisture dependent damage parameter for EA9321 was calibrated usin...
